  1. Thanks everyone for your help and sorry for the long inactivity -- I just pushed this to the side and the papilio has been catching dust for half a year. What I tried since the last posts: - Got a second Retrocade Megawing -> same issues with that, so it's not the extension board - tried the whole thing on my work laptop with Linux64 instead of Win10/64, which was the only system I had on all of my personal machines - set up an extra machine with Win7/32, since I figured the whole Papilio Platform seems to like 32 bit OSes - also tried your loader, Felix -> behaves the same - and, lastly, a different USB cable When I load the bitfiles from the Win7 machine, I actually get Audio output and it even reacts to MIDI, but the firmware seems to behave erratic. LCD contrast is barely readeble (the "lcd contrast fix" bitfile doesn't display any text at all). One time it always played a high note when I released all keys from the midi keyboard. Songs from the menu always restart playback every 1/2 second while in the menu and play back normally when I switch to the next menu. Writing the firmware to SPI flash takes about 262 seconds (SPI exec time; scan, erase and verify enabled), is that a normal time? Best Regards, Henrik
  2. Hi Felix, thanks! I tried ROMVault, it failed over the USB hub. Then I connected directly and now the Arcade MegaWing works! (At least I get VGA output, I didn't connect a gamepad yet and the PCB buttons don't really do that much). I also tried to program the RetroCade without a hub in between but I get the same symptoms. I think I'll test if the voltages are stable and maybe how much current is consumed.
  3. Okay now I see the ascii table on com7 and also every even pin toggles (didn't test everyone though). The com ports use the standard FTDI driver, not a specific papilio serial driver, on my machine, might that be causing problems? I guess the drivers were already there because I used FDTI UART cables on this machine before. The program seems to only run once I restart the papilio board after programming (takes about 3 seconds to start then). I also tried the same with the retrocade wing and firmware, but even after restarting it doesn't show any lifesign.
  4. Hi Jack, thanks for the quick response. I tried the bin file you supplied, the board is powered by USB now, and all the pins from port A,B,C that I tried are constantly at 3.3V. The oscillator itself seems to be running, the messy signal is just because I dont have a proper scope available atm. About the ASCII-table: Which serial port do you mean? The SPI close to the USB controller? Or is there a UART over USB available over hterm etc? Edit: the loader's last message after programming is: Could not access USB device 0403:6010. Best Regards, Henrik
  5. Hi, I just received a Papilio Pro from seedstudio(china) and the two megawings (retrocade synth and arcade) from a german distributor about two weeks ago, and the megawings both don't work. I post this in the Papilio Pro board to find out, if the PP is broken, or both MegaWings are broken (might also be, they look a bit used) I tried the retrocade synth first with papilio loader 2.8: - writing to SPI flash works, verifying also, but the time it takes seems to vary a lot -> verifying was OK every time I tried - writing to FPGA also seems to work fine, I also switched the loader to expert mode like suggested in another thread - no reaction to MIDI input (double checkt the cable and keyboard I used) - at one point, a demo started to play ("welcome to re-re-retrocade" and then some music), but it sounded really glitchy (first some voices sounded like they skipped a few notes, but it got worse to the point that hardly any notes were played) - most times the display stayed blank, once I got to the space invader menu where i could select midi channel etc. with the joystick, but still no reaction to the keyboard - when I started the programming operation, the space invader thing showed on the display during the programming process, but disappeared when the programming was done Then I also tried the Arcade MegaWing with the latest version of the software, loaded a game, but my VGA monitor didn't display anything. I didn't test this one a lot though (if it would have worked I could have been sure the Retrocade Wing was malfunctioning). I use Win10 and enabled the Testmode to install the unsigned drivers before I installed both MegaWing's software. Question: Is there an easy way to verify that the Papilio pro board is the broken one? Some diagnostic tool or something? I don't really want to send it back to china before I know for sure which board is damaged. Would be happy about any suggestions what else I could try. Thanks in advance, Henrik
